I have n OS 65 LA thatr is 8 years old. I bought it new back in 01 and broke it in per the manual. I then flew it for about 2 dozen flights with no problems at all. I did loops and rolls. It is on a trainer a/c so no heavy duty manuvers. The engine/model sat in my garage all these years unused due to lack of time to have a life beyond work. That has all changed now and Iam ready to fly again. I stripped and recovered my model. While doing that I put the engine on a test stand and ran a couple of tanks through it. I actually stored it correctly as there was no corrosion anywhere. The engine ran well. But Ihave finished my re-covering job. m Installed the engine. And now I cannot get it to run correctly. It starts fine. But when I advance the throttle it dies. Needle valveadjustments do not seem to have any effect on top end. If I try to adjust the needle valve at idle, RPM drops rapidly. HELP!!! I would love to get backin the air soon but as of now the engine is totally unreliable. Any suggestions?

Istarted out running 10%. I am running 15% now at the suggestion of my local hobby shop.
